EDWARD B. HUBER, OF ST. LOUIS, MISSDURI, ASSIGNOR OF ONE-HALF TO FREDERICK L. POHLMANN, OF ST, LOUIS, MISSOURI.

VAIPOBrBURNER.

Be it known that I, EDWARD R. HUBER, a citizen of the United States, residing at St. Louis, in the State of Missouri, have in- .vented certain new and useful Improve merits in Vapor-Burners, of which the following is a specification.

This invention relates to vapor burners and has for its primary object to provide an improved-construction, combination and arrangement of parts in devices of this character.

Figure 1 is an axial section of one embodi- I ment ofmy invention. Fig. 2 is a similar section of another embodiment of the same.

Referring more particularly to the draw ings and to the embodiment shown in Fig. 1, the burner com rises the combination and arrangement of vapor chamber having an annular convex portion with radially arranged burner openlngs and an inner vapor chamber communicating therewith through a plurality of radially disposed ports or passages and a reticulated screen or gauze withinthe inner vapor chamber through which the vapor delivered to said burner must pass in its passage through the burner. The lower wall of the outer chamber is suitably formed to deflect the gaseous mixture upwardly toward the burner outlet openings. Said outer chamber is constituted in the present embodiment by a base member or casting 1 having a circumferential flange 2 providing an annular shoulder 3 upon which rests the outer circumferential edge of a cap member or casting 4: which rests upon the base member 1 an is releasably secured thereto in a manner to be hereina ter pointed out. The cap casting 4 is provided with a plurality of outlet 0 'enings .5 disposed in a ring about the axis 0 the urne-r, said openings being preferably in the form of radially arranged slits in the burner casting 4, Wl'llCh casting is in the form of a circular gallery, as shown on the drawing. In the present embodiment, said cap casting 4 is provided with an Specification of Letters Patent. Application filed. November 14, 1910. Serial No. 592,191.

. aperture in the base casting 1. In order to provide means for releasably securing the cylindrical shell 8 in position as well as for holding the cap 1 in place upon the base 1, the stem 9 is provided exteriorlywith a threaded portion 10 for the reception of a lock nut 11 which is adapted to be screwed upon the threaded portion 10 into abutment with an annular shoulder or boss 12 formed on said base member 1. A vapor suppl pipe 13 is connected to the inlet shell 8, pre erably, by being threaded to the interior wall of the stem 9, being therebv adapted to discharge u wardl into said inlet shell or chamber. ylindrically disposed within the inlet shell or chamber and forming an approximate continuation of the supply pipe 13, is a; reticulated sheet 14 in the form of gauze which permits the outward passage of vapor therethrough but prevents any possible retrograde passage of flame. A plurality of portsor passages 15 are radially disposed in the cylindrical wall of the inlet chamber shell 8, saidports by reason of the upper portion of the shell 8 being larger than the stem 9, being separated from the gauze 14 by an annular space. By reason of this construction, the vapor is enabled to pass through the entire lateral area of the gauze 14 into the annular chamber between it and the passages 15 while at the same time the capacity of said passages 15 is in no way restricted by having the gauze 14 cover the same.

Referring now to the embodiment shown in Fig. 2, the arrangement of the chambers and passageways is substantially the same as that shown in Fig. 1, the burner being constructed in a difierent manner as will now be explained. Thus, the cap casting 4 of Fig. 1 is replaced by an integral, casting comprising an annular ring ortion 16 provided with radially disposed burner openings 17 and having its central portion entirely closed with an integrall formedplate 18 which forms the top wa lot the inlet chamber. Said inlet chamber is provided of the same shape as in the former embodiment by having an integral portion of the cap casting depending from the central plate 18 and having its reduced stem portion 19 adapted to receive a base member or casting 20. A supply pipe 21 is secured to the depending'end of the stem 19 while the base member is locked in position by a lock nut 22.

The principle of operation of my improved burner now will be readily understood and briefly stated is as follows. Referring'to Fig. l, the vapor mixed with air is conveyed through the supply pipe 13 into the inlet chamber within the gauze 14. and passes therethrough into the annular chamber interposed between said gauze 14: and the ports 15 through which the vapor passes into the outer chamber, to be discharged through the burner openings 5. It will be seen, therefore, that as the vapor passes through the burner, it is caused to expand radially outward in all directions, passing from the smallest chamber within the gauze 14 into a larger chamber without the gauze l4: 'and thence outwardly into the largest chamber betweenthe base casting l and the cap casting 4:. During its progress through these chambers, the pressure becomes gradu ally reduced, the general construction and arrangement of parts serving to prevent sudden variation. At the same time, by reason of its passage through the screen 14: and the perforations 15, the ingredients of the gaseous mixture become more intimately mixed and the mixture made uniform throughout. By means of the features of construction shown and described, all flaring oi the flame from the burner openings 5- is avoided, inasmuch as the various passages through which the vapor passes provides eflicient means for governing the passage of the vapors through the burner with the resuit that a steady burning flame is produced. It is to be noted that the several parts of the burner in either embodiment are readily accessible for cleaning and repair work, should such be necessary. In either of the embodimentsshown in Figs. 1 and 2, the shoulder formed by the enlarged portion of the inlet shell, is spaced from the upper annular face of the depending boss portion of the base casting so that the locking nut may be tightened beyond the point where the peripheral edge of the cap casting is drawn tight upon the peripheral seat or shoulder on the base casting. Inasmuch as the centrally disposed inlet shell is separated from the peripheral edge of the cap a (or 16) there will be a certain amount of resiliency which, if the lock nut be moved enough, will result in dram ing a large portion of the inlet shell down into the annular central abutment or boss of the base casting. The cap and basecastings are, therefore, resiliently pressed together.

What I claim is: l

l. The combination with a supplypipe,

of an inlet shell surmounting said pipe, a burner cap, means for holding said cap against endwise movement in one direction relative to said inlet shell, a burner base slidable axially along said shell into andout of abutment with the periphery of said cap, and threaded means mounted on said shell and cooperating with the first said means for forcing said base and cap together.

2. In a device of the character described, the combination with a supply pipe, of an inlet shell surmounting said pipe, a burner cap, means for holding said burner cap against relative movement to said inlet shell, aburner base slidably engaging said inlet shell and adapted to form a closeperipheral joint with said cap, and a lock nut threaded upon the exterior wall of said inlet shell .a hub slidably engaging said cylindrical portion, and a lock nut for drawing the base member tightly against the cap member.

4:. In a device ofthe character described,

the combination with a supply pipe, of an inlet shell surmount-ing said pipe and provided with apertures in the lateral walls thereof, an outer burner shell comprising a base portion inclined upwardly and outwardly around said inlet shell, and a burner cap convexed upwardly and having burner openings in the convex portion thereof, said convex portion extending in a' ring around said inlet shell.
